Question about Vizio GV42L 42 in. LCD Television

1 Answer

TV flickers when turned on. This affects both sound and picture contantly and quickly going in and out. Amber light is on when TV is off, and white light is on with TV. I turned on the TV and it was normal, then tried again and it flickered. TV was on when we experienced a power blip and it went out for a half a second. It is hooked up to a surge bar, and all other components on the bar are OK, just had to reboot.

    Sounds like the surge bar didn't do it's job. Did you have to reset the surge bar after the power blip?

This TV has built-in MOV's, the exact same thing you find in the surge protection bars... perhaps one of those has done it's job and fried OR something totally different is working a mess on the PwrSup board, like the 450V cap that is always powered at least under 150V while the set is off and pluged in with amber light.

If you don't know you way around PWM electonics your next step may be to call Vizio. Good luck on getting this resolved to your satisfaction for less than $300.

Do you have back light when turning on the TV? if you do then just replace the main board should resolve the problem. if you do not have back light, you will need to replace the inverter board(s) depending on your model. The inverter board(s) is located on the left side of the TV facing back of TV. you may have two inverter boards depending on your model. the other is located on the right side of the TV. Both mount vertically.
